If you've ever owned a young animal, whether that's a puppy or a particularly suicidal cat, you know they have a strange desire to chew on power cords. This causes all sorts of problems. Over on Cool Tools they recommend cheap plastic tubing to keep your cords safe.

The tubing is a 1/4-inch Split Loom, like this one that you can get 100 feet for about $12. Just wrap your cords in the tubing, and you're all set. Easy as that. The best part is you don't have to deal with those weird, expensive, and foul smelling solutions you often find at pet stores.
